How can I convert my Code written in PyCharm and Env Conda to an Executable?

Question

i wrote a code which works on PyCharm, with Conda but I am not able to use auto-py-to-exe because the exe never works. This is the code:

import os
from PyPDF2 import PdfReader, PdfWriter
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas
import tkinter as tk
from tkinter import filedialog, simpledialog, OptionMenu


def save_recent_output_folders():
    with open("recent_output_folders.txt", "w") as file:
        for folder in recent_output_folders:
            file.write(folder + "\n")


def choose_input_pdf():
    file_paths = filedialog.askopenfilenames(title="Wählen Sie die Eingabe-PDF-Dateien",
                                             filetypes=[("PDF Dateien", "*.pdf")])
    selected_files.clear()
    for file_path in file_paths:
        file_name = os.path.basename(file_path)
        selected_files[file_name] = file_path
    input_pdf_var.set(", ".join(selected_files.keys()))


def choose_output_folder():
    folder_path = filedialog.askdirectory(title="Wählen Sie den Ausgabeordner")
    output_folder_var.set(folder_path)
    recent_output_folders.insert(0, folder_path)
    update_output_folder_menu()
    save_recent_output_folders()


def update_output_folder_menu():
    output_folder_menu['menu'].delete(0, tk.END)
    for folder in recent_output_folders:
        output_folder_menu['menu'].add_command(label=folder, command=lambda f=folder: output_folder_var.set(f))


def extract_and_save_vorletzte_seite(input_file_path, output_file_path):
    pdf = PdfReader(input_file_path)

    if len(pdf.pages) < 2:
        result_label.config(text="Die PDF hat weniger als 2 Seiten.")
        return

    vorletzte_seite = pdf.pages[-2]

    writer = PdfWriter()
    writer.add_page(vorletzte_seite)

    with open(output_file_path, 'wb') as output_file:
        writer.write(output_file)

Can someone please help me?

I tried it many times but it never worked. I am not at home so I can´t use another machine. Can someone please help me? It would also help to upload the exe. I also tried to use pyinstaller but it also didn´t work
